As a Wikivoyage editor, I think we would be disappointed to see most of the features listed under "Implications" lost. We maintain printability as a major goal of the site, so features that make the PDF look more like a professionally printed book and less like a printed-out webpage are highly valued. Also, as a travel site, we expect our users who print our guides to want a portable format, meaning something quite a bit smaller than A4.
Speaking personally, I think features like tables of contents and indices are extremely useful and it would be nice to retain the former and add the latter.
